Marissa Mayer Shuts Down Sunshine, Launches AI Assistant Startup Dazzle with $8M Seed Round

Former Yahoo CEO Marissa Mayer is officially back in the startup game, pivoting from a stalled consumer app to the generative AI revolution. After shuttering her six-year-old startup Sunshine, Mayer has launched Dazzle, a new company focused on building next-generation AI personal assistants. According to TechCrunch, the new venture has already raised an $8 million seed round at a $35 million valuation, signaling strong investor confidence in her new direction.

From a Flop to a Fresh Start

Mayer's previous company, Sunshine (originally Lumi Labs, founded in 2018), struggled to find its footing despite her high profile. Its flagship contact management app drew criticism from privacy advocates, and a later pivot into photo-sharing and event management failed to gain traction, with critics pointing to an outdated design. Mayer candidly admitted to TechCrunch that Sunshine's mission was too "mundane" and the problems it tackled weren't large enough for a significant impact.

The Sunshine team began prototyping Dazzle last summer and, as Mayer put it, "realized that this was something that we were much more excited about." The ambition and opportunity of the new AI project quickly eclipsed their previous work. As part of the transition, investors in Sunshine, which had raised a total of $20 million, received 10% of Dazzle's equity.

A Stamp of Credibility from a Top VC

The $8 million seed round was led by Forerunner's Kirsten Green, a venture capitalist known for backing iconic consumer brands like Warby Parker, Chime, and Dollar Shave Club. Green's lead investment is a significant vote of confidence, especially given Sunshine's lackluster performance. It suggests that Dazzle is well-positioned for what Green calls the coming wave of consumer-facing AI businesses.

Mayer's Quest for a Third Act

Before her tumultuous tenure at Yahoo, Mayer was Google's 20th employee, where she was instrumental in shaping the look and feel of products like Search, Maps, and AdWords. "I have had the rare privilege of being at two companies that really changed how people do things," Mayer said. "I really aspire to build a product that has that kind of impact again." Dazzle is currently in stealth mode, with its website password-protected, and is expected to launch early next year.
